The Steelmate USA Front and Rear Parking Assist System with 8 Sensors includes 4 front and 4 rear sensors, two displays (front sensor display, rear sensor display), and active front sensor monitoring during backup stages. The displays show distance of object in feet, with LED and audible beep prompts. The additional front 4 sensors act as an aid while pulling into or out of a tight space and when reversing the 2 front corner sensors will stay on to monitor the vehicles corners.
